As shown in the figure below, data is collected from the IO port of the MSP430 microcontroller and then sent to the computer. The computer receives the data and displays the graph of the second figure...
Is there a chip solution with dual adjustable PWM frequency and duty cycle? Can it be controlled by two voltages, one to control the output frequency and the other to control the output PWM?...
The 12V controlled by the controller is used to supply power to the outside. I plan to use this optocoupler for isolation in case of reverse connection. I don't know if this is correct. I hope netizen...
:funk: I just started to learn MSP430, and now I am using MSP430f2132. I wrote a program to communicate between MSP430 and ADC via SPI. Now I want to simply test whether the MSP and ADC can communicat...
